REVERSIBLE WINDOW.

Application filed July 9, 1917.

To all whom it may concern Be it known that I, NICHOLAS M. STARQK, acitizen of the United States, and resident of Milwaukee, in the countyof Milwaukee and State of Wisconsin, have invented certain new anduseful Improvements in Reversible Windows; and I do hereby declare thatthe following is a full, clear, and exact description thereof.

My invention relates to new and useful improvements in slidable windowsashes, particularly those which are pivoted to swing out of alinenientwith the window frame.

It is primarily an object of this invention to provide means wherebywind-ow sashes may be pivotally as well as slidably mounted in a windowframe for permitting ready access to both the inside and outside of thepanes thereof. This provision allows both the inside and outside of thewindow sashes to be cleaned from the inside of the room.

In carrying out this principal object, minor objects of the inventionconsist in an improved sliding connection between the sashes and theadjacent portions of the window frame; any means for normally retain-'ing the sashes in vertical position and against accidental movement outof alinement with the frame; and any means for retaining the sashes indifferent positions when moved out of alinement with the frame.

vVltl'l the foregoing objects and advantages in view the inventionresides in th novel features of construction combination and arrangementof parts which will be hereinafter more particularly described andclaimed, and shown in the accompanying drawings wherein:

Figure 1 represents an upper left hand corner of a window frame showingthe portion of an upper sash therein, parts of the frame and sash beingbroken away and shown in section to more clearly illustrate certainfeatures of theinvention.

Figs. 2 and 3 are horizontal sections taken substantially on the planesof the lines 2-2 and 33 of Fig. 1.

Fig. 4 is a vertical sectional view through a window frame showing themanner in which the sashes thereof may be swung to certain positions.

In the illustrated embodiment of my invention, it will be noted that theimprovements Specification of Letters Patent.

are applied to ordinary wooden sashes and frames. It is obvious,however, that the same arrangement could be also used with all metalframes and window sashes with only slight modifications. It will also beapparent that the invention be applied to ordinary windows already inuse as well as those which are just being constructed.

The frame 1 is of ordinary construction, it being provided with theusual weight box 2 and the exposed portions which are covered by a trimof any preferred design. The frame is also designed to receive upper andlower sashes 3 and @i respectively which slide vertically in channelsformed in the opposite side walls of the frame by means of the outerstrips 5 of trim material and the head 6.

In order to apply my invention, it is necessary that the sashes 3 and ibe somewhat narrower than the usual sashes provided for standard sizeframes, inasmuch as the improvements are disposed between the side wallsof the frames and the adjacent side edges of the sashes. The oppositeside edges of the sashes have a substantially H-shaped sheet metal strip7 disposed thereover, the arms 8 of the strip being engaged with theinner and outer sides of the sashes to which they are secured by screwsor the like 9. The arms or flanges 10 of the strip 7 are disposedsubstantially in alinement with the arms 8 and project beyond the edgesof the sashes as clearly shown in Figs. 2 and 3. They may be formed inany desired manner, but are preferably constructed in the manner shownthat is to say, by bending the strip longitudinally upon itself adjacentto its longitudinal edges. This is also most desirable, inasmuch as thestrip is of light sheet metal.

The arms or flanges 10 being disposed longitudinally throughout thelength of the sashes form one part of cooperating guides for movablecontact plates 11, one of which is disposed on each side edge of eachsash. These plates are, also, in the form of strips of sheet metal, theybeing preferably longitudinally concaved with their outer edges bentlaterally as at 11 for engagement with the outer surfaces of the flanges10. Substantially U-shaped reinforcing plates 12 are disposed betweenthe contact plates and the adjacent members 7 and the laterally bentedges 13 thereof are spaced from the similar portions of the contactplates and are designed toengage the inner surfaces of the flanges 10.

Expansion coil springs 14 are also disposed between the contact plates11 and the adjacent edges of the sashes, whereby the former will becontinually urged outwardly away from said sashes. The combination ofthese springs, however, will be overcome by pressure on the contactplates so that the latter will be enabled to be moved inwardly, andduring both inward and outward movement they will be guided by theguides formed by the flanges 10, 11 and 13.

Positioned between these parts and the adjacent walls of the frame arecarriages 15, which are substantially U-shaped, the distance betweentheir arms 16 being approximately the width of the channels formedbetween the strips 5 and 6. These carriages are each of a lengthsubstantially equal to the height of the sash with which it is used andare provided with rollers 17 for sliding contact with the frame. To formbearings for the rollers, the arms 16 of the carriages are bentlaterally inwardly and then toward the outer face thereof, as shown at18. Said outer faces of the carriages are longitudinally convexed andare adapted to engage with the concave faces of the contact plates 11. I

Each sash has a pivot stud 19 extending from its opposite side edgessubstantially midway the length thereof, said studs being projectedthrough the contact plates 11, the reinforcing plates 12, and the convexfaces of the carriages, thereby pivotally mounting said sashes to theadjacent carriages. Since the springs 14 will normally urge the contactplates outwardly, it is obvious that there will be considerablefrictional engagement between said plates and the carriages so that apivotal movement of the sashes will be re stricted, thus preventingaccidental movement of said sashes. They may readily be slid verticallyin the frame, however, and retained in any position therein by the usualcounter-balancing weights disposed in the weight boxes 2, the sash cords20 for these weights being drawn over pulleys 21 and secured to thecarriers by means of cross strips 22 each connecting the portions 18thereof.

In order to dispose the inside of one of the window sashes inwardly toclean it, or for any other purpose, it is swung about the pivot studsthereof, as shown by the dot and dash lines in Fig. 4. Because of thefrictional engagement between the contact plates and the carriages, thesashes may be main- Gopies of this patent may be obtained for tainedpractically in any angular position relative to the frame. Furthermore,it is also obvious that since the pivotal connections between the sashesand the frame are movable, said sashes may be reversed regardless oftheir position in the frame. Also, said sashes may be slid vertiallyinthe frame after or during pivotal movement thereof, as well as before.

I claim:

The combination with a frame and a window sash or the like disposedtherein, of means of mounting the window sash or the like for slidingand rotative movement in the frame comprising a plate substantially Hshaped in cross section, the longitudinal flanges extending from oneside of the plate being secured to the inner and outer sides of the sashor the like at one edge, the longitudinal flanges extending from theother side forming one part of cooperating guides, a movable contactplate longitudinally concaved and having its longitudinal edgesbentlaterally for sliding engagement with the outer surface of the guideflanges of the H-shaped plate, a reinforcing plate substantiallyU-shaped in cross section and disposed between the H-shaped plate andcontact plate, said reinforcing plate having its flanges engaged withthe inner surface of said contact plate and spaced from the flangesthereof to slidably receive the guide flanges of the H-shaped platetherebetween, a carriage U-shaped in cross section disposed between saidcontact plate and the adjacent wall. of the frame, the face of thecarriage being longitudinally convexed for engagement with the concaveface of the contact plate, a pintle extending from the H-shaped plateand slidably disposed through the reinforcing plate and contact plate,said pintle being journaled in the convex face of the carriage, a pairof expansion springs positioned between the reinforcing and the H shapedplates and disposed one on each side of the pintle, roller bearingsformed on the carriage by bendinnithe flanges the eof latorally inwardlyand then toward the outer face thereof, rollers disposed in saidbearings for sliding contact with one wall of the frame, and slidingpivotal connection be tween the other wall of the frame and the pglzjacent edge of the window sash or the In testimony that I claim theforegoing I have hereunto set my hand at Milwaukee, in the county ofMilwaukee and State of Wisconsin.
